Hello from Jordan

Hi Sylvia Bernstein
I work for the Royal Botanic Garden in Jordan and looking to establish an aaquaponic project with fish and vegetables at our permaculture site. I have two questions, one about the water quality sine our irrigation water is infected with pathogens (irrigation water), what will be the best methods to improve such water for fish, can we do it by wetland method? can we use bio-char for this? , second question, how we can get copy of your book, Mohammed Ayesh
